How to return a code number to system in C#?

hello,

I'm new to C# so forgive me for a simple/silly question. In C/C++ you can return a different code number if an error has occurred, for example:

int main() {
....
if (someError)
return 3; // 3 may mean a specific error
....
return 0; // 0 == successful
}

how can this be done in C#? Whatever I do in the C# code, it seems that the system and applications calling the C# application get code 0.

thanks

The above (just changing the case) should work fine, but an alternative
is to use Environment.Exit.

An example of the "easy" way:

using System;

class Test
{
static int Main()
{
return 3;
}
}

Run the program and then print out %ERRORLEVEL% and it will be 3.
 
Hi Jon,

I was about to write a C++ app that would check the returned value, but is there any reason why VS .NET always shows that the application has exited with code 0 in the tab when debugging?
thanks

Don't know, I'm afraid :(
